FAN-MOTOR ADAPTERS Specification of Letters Patent.

' Application fi1ed August 2,1905. Serial No. 272,439.

citizen of the United States, and a resident of Wllkinsburg, n the county of Allegheny and State of Pennsylvania; have invented a new and useful Improvement in Fan Motor Adapters, of which the-following is a specification. T

My invention relates to means for adapting a bracket to be mounted either in alinement with its base or at an angle ofsubstantially ninety degrees therewith, and particularly to means for adapting a relatively small electric motor for mounting in either a vertical or a horizontal plane.

The object of my invention is to provide an adapter for amotor-bracket that shall be simple and durable in construction and permit a rotary adjustment about the center -line of the bracket and that may be inserted or removed without disconnecting the su plyconductors which ordinarily pass throug 1 the hollow bases and brackets of such motors.

In the prior art relatively small power-n10- tors or fan-motors were usually constructed with hollow bases and brackets, through which the motor-leads were passed, the two portions being assembled in alinement for mounting on a horizontal plane and provided with an elbow-adapterfor mounting on a vertical plane. With this arrangement it was necessary to disconnect the motor-leads and pull them through the adapter whenever the mounting was changed from the one plane to the other. To obviate this objectionable feature, the adapter of my invention is provided with a slot cut through one wall in such a manner that the adapter may be inserted or removed without disconnecting the supplyc'onductors.

My invention is illustrated in the accompanying drawings, in which Fi ure 1 is a side elevation of a motor provide with an adapter constructed in accordvance therewith, t e base and bracket being shown partially in section to disclose the ada ter; and Figs. 2 and 3 are respectively a I p an and a sectional elevation of the adapter of Fig. 1'.

Referring to the drawings, an adapter 1 is inserted between a bracket 2 and the sup- 1porting-base 3 of a motor 4 and comprises a ollow elbow, which is provided with a por- 1 tion 5, that engages a socket in the base 3,

and with a socket 6 to receive the end portion 7 of the bracket 2. The adapter 1' is ro-- vided with a slot or saw-cut 8, through w ich a plurality of conductor-leads 9 and 10 may pass. The portion 7 of the bracket 2 which engages the socket 6 of the adapter 1 has the same form and dimensions as the portion 5 of the adapter 1, so that it may engage. the base 3 when the adapter is removed, in which case with the base.

hen the adapter is omitted, the bracket is rotatably mounted directly upon the base and is fastened thereto by a set-screw 11, which is threaded into the base and engages a groove 12 in the portion 7 of the bracket. v

The adapter 1 may be clamped to'the base by the set-screw 11 and is provided with apin 13, which engages a small hole in the base 3 and serves to prevent the rotation of the adapter about the center line of the base. The motor-bracket, however, is rotatably mounted with respect to the adapter, a setscrew 14 being provided to enga e the groove 12 in the portion 7 of the brac et; but the two parts may be clamped together by means of a thumb-screw 15, which is screw-threaded into the adapter 1.

I desire that all variations in size, form, or arrangement of details which effect similar results and which do not materially depart cluded in its scope;

Iclairn as my invention 1 A motor-adapter that com rises a hollow elbow having a slot throng which the circuit connections of the motor may pass when the adapter is removed.

2. A motor-adapter that comprises a hollow elbow having a slot in one side thereof.

3. The combination with an electric motor,

a plurality of conductorleads that pass through said hollow members, of a removable adapter which connects the bracket with the .base and is provided with a slot through which the leadsmay pass when the adapter is removed.

I a hollow bracket, a hollow base therefor, and one or more conductor leads that pass the bracket will be supported in alinement 4. The combination with an electric motor,

from the spirit of'my invention shall be 1n- I a hollow bracket, a hollow base therefor, and

through said hollow members, of an adapter that determines the angle between the center lines of the bracket and the base and is provided with a slot through which the leads may pass when the adapter is removed and replaced.

5. The combination with an electric motor, a hollow bracket, a hollow base therefor, and one or more conductor leads that pass through said hollow members, of an ada ter comprisin a hollow lead-connector w ich supports t e motor-bracket in a line that is substantially perpendicular to the center line of the base, said hollow connector being provided with a slot or cut through which the leads may pass when the adapter is removed and re laced.

6. T e combination with an electric motor, a hollow bracket, a hollow base therefor, means for ,sup orting said bracket in alinement with said base, and one or more conductor-leads that pass through said hollow members, of an adapter comprising an elbow that may be inserted between the base and bracket and supportsthe bracket at an angle of substantially ninety degrees to the center line of the base, said elbowbeing provided with a cut through which the leads may pass when the adapter is inserted or removed.

7. The combination with an electric motor, a hollow bracket, a hollow base therefor, and one or more conductor leads that pass through said hollow members, of an adapter that comprises a hollow elbow provided with a socket which is engaged by the end of the hollow bracket and with a ortion that engages a socket in said ho low base, said adapter being provided with a slot or cut through which the leads may pass when it is removed and replaced.

8. A hollow adapter for electric motors that is open at both ends and has a side slot for the insertion and removal of conductors.

In testimony whereof I have hereunto subscribed my name this 31st day of July, 1905.
